>>billions?  all you need are thousands of years.  the speciation of
haplochromine cichlids in lake victoria (from one species to over 300
species) took just a few thousand years.  a blink of an eye in biological

tsuh yang<<

Even more rapid is what I refer to as the 'vegetative evoloution' in aroids!
Buy a plant of Xanthosma atrovirens (the one with the little 'frills' on the
underside of the leaf blade) and watch it happen before your very eyes from
one 'pup' to the next.   Taro (Colocasia esculanta) is another 'quicke'----
the Hawaiians produced over 200 cultivars which are VERY different one to
the other in just a few thousand years, and if we did not know better
may/could be described as different 'species' by the unknowing, and by
vegetative selection!!   A VERY short 'blink' indeed.
